http://issues.apache.org/bugzilla/show_bug.cgi?id=35377 Summary: ConcurrentModificationException in OptimisticMapWrapper.copyChangesToConcurrentTransactions Product: Commons Version: 1.0 Final Platform: Other OS/Version: other Status: NEW Severity: major Priority: P2 Component: Transaction AssignedTo: commons-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] I've found (another) thread safety problem in commons-transaction 1.1b2. OptimisticMapWrapper.copyChangesToConcurrentTransactions() is iterating over "activeTransactions" without synchronizing around the iterator use. Here's the trace that I am seeing. Note this only happens rarely and under heavy load. I am seeing this though slide when running with "sequential-mode=off" in Domain.xml 14 Jun 2005 07:31:25 - org.apache.slide.transaction.SlideTransaction - WARNING - Commit failure: Resource manager [EMAIL PROTECTED] Error code java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(HashMap.java(Compiled Code)) at java.util.HashMap$KeyIterator.next(HashMap.java(Compiled Code)) at org.apache.commons.transaction.memory.OptimisticMapWrapper.copyChangesToConcurrentTransactions(OptimisticMapWrapper.java(Compiled Code)) at org.apache.commons.transaction.memory.OptimisticMapWrapper.commitTransaction(OptimisticMapWrapper.java:155) at org.apache.commons.transaction.memory.OptimisticMapWrapper.commitTransaction(OptimisticMapWrapper.java:127) at org.apache.commons.transaction.memory.jca.MapXAResource$MapTransactionalResource.commit(MapXAResource.java:111) at org.apache.commons.transaction.util.xa.AbstractXAResource.commit(AbstractXAResource.java(Compiled Code)) at org.apache.slide.store.mem.AbstractTransientStore.commit(AbstractTransientStore.java:106) at org.apache.slide.transaction.SlideTransaction.commit(SlideTransaction.java(Compiled Code)) at org.apache.slide.transaction.SlideTransactionManager.commit(SlideTransactionManager.java(Compiled Code)) at org.apache.slide.common.NamespaceAccessTokenImpl.commit(NamespaceAccessTokenImpl.java(Compiled Code)) at org.apache.slide.webdav.method.AbstractWebdavMethod.run(AbstractWebdavMethod.java(Compiled Code)) at org.apache.slide.webdav.WebdavServlet.service(WebdavServlet.java(Compiled Code)) at javax.servlet.http.HttpServlet.service(HttpServlet.java(Compiled Code)) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java(Compiled Code)) at org.mortbay.jetty.servlet.WebApplicationHandler$Chain.doFilter(WebApplicationHandler.java(Compiled Code)) at com.ris.manager.gateway.http.IPAddressRestriction.doFilter(IPAddressRestriction.java(Compiled Code)) at org.mortbay.jetty.servlet.WebApplicationHandler$Chain.doFilter(WebApplicationHandler.java(Compiled Code)) at org.mortbay.jetty.servlet.WebApplicationHandler.dispatch(WebApplicationHandler.java(Compiled Code)) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java(Compiled Code)) at org.mortbay.http.HttpContext.handle(HttpContext.java(Compiled Code)) at org.mortbay.jetty.servlet.WebApplicationContext.handle(WebApplicationContext.java(Compiled Code)) at org.mortbay.http.HttpContext.handle(HttpContext.java(Compiled Code)) at org.mortbay.http.HttpServer.service(HttpServer.java(Compiled Code)) at org.mortbay.http.HttpConnection.service(HttpConnection.java(Compiled Code)) at org.mortbay.http.HttpConnection.handleNext(HttpConnection.java(Compiled Code)) at org.mortbay.http.HttpConnection.handle(HttpConnection.java(Compiled Code)) at org.mortbay.http.SocketListener.handleConnection(SocketListener.java(Compiled Code)) at org.mortbay.util.ThreadedServer.handle(ThreadedServer.java(Compiled Code)) at org.mortbay.util.ThreadPool$PoolThread.run(ThreadPool.java(Compiled Code)) Patch to follow. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
